Comparison of standing and sitting position used in surface topography trunk assessment
Journal Title: Postępy Nauk Medycznych - Year 2012, Vol 25, Issue 6
Abstract
<b>Introduction.</b> Children with idiopathic scoliosis need x-ray rechecks. Adams test and Angle of Trunk Rotation (ATR) measurement with Bunnell scoliometer are standard methods of trunk assessment. Surface topography examination (ST) enables three-dimensional, fast and accurate trunk analysis. This study was conducted to evaluate a sitting position with trunk kyphotization in ST examination (ST-Sit) used for assessment of scoliotic patients’ trunk deformations.<br><b>Material and methods.</b> 113 girls were examined, aged 10 to 18, mean 14.0 ± 2.1. Cobb angle mean value was 41.2° ± 16.7°, ranged from 10° to 95°. Based on x-ray imaging, ATR scoliometer measurement and ST examination, the following parameters were assessed: spinal length, POTSI, Hump Sum and number of spinal curvatures in frontal plane.<br><b>Results. </b>ST revealed statistically significant difference between standing and sitting position regarding: spinal length, POTSI and Hump Sum. Strong correlation occurred between Hump Sum parameters measured with scoliometer and during standing position in ST (ST-Stand). Hump Sum results of scoliometer examinations and ST-Sit revealed very strong correlation. There was no statistically significant difference between rotational values measured with scoliometer and during ST-Sit. Higher number of spinal curvatures was detected in ST-Sit compared to X-ray examination and ST-Stand.<br><b>Conclusions.</b> ST-Sit position (1) is easy to perform, (2) more stable than ST-Stand, (3) eliminates influence of pelvis asymmetry on trunk, (4) correlation between scoliometer measurement and ST-Sit was stronger than between scoliometer measurement and ST-Stand, (5) trunk kyphotization allows higher sensitivity of rotational deformity evaluation (6) and better visualization of spinal curvatures.
